Subject: Cropping with Hauppauge HVR-1900
Date: Fri, 26 Jun 2009 11:46:55 +0200 [thread overview]
Message-ID: <4A44990F.5050901@aokks.org> (raw)
Hello,
I have a Hauppauge HVR-1900 which works fine with the pvrusb2 driver.
However because most TV channels now air with 16:9 content inside 4:3
images, I would like to crop out the top and bottom black bars before
encoding via the hardware MPEG2 encoder. I tried using the ctl_crop_top
and ctl_crop_height in /sysfs as well as the --set-crop option of
v4l2-ctrl but only received error messages indicating a value out of range.
The card has a cx25843 which should support cropping. Does anyone know
how to get this feature to work ?
Thanks in advance for the help,
Joseph
